The Threshold Institute specializes in pain. Institute
director Lady Olivia fondly remembers a series of tests run
on girls who have experienced a numbing of sensation due to
brutal treatment at the hands of a family member.

Charlie was spanked senseless by her stepfather and now
wants to feel pain again on the road to recovery. Olivia
understands, and spanks and flogs her as part of her
unorthodox therapy. She also suspends her by wrists and
ankles, uses tack gloves, clothespins and a rather nasty
pinwheel.

Next, rival siblings Chloe and Cleo are hauled down to the
dungeon and flogged, clamped, spanked, whipped and humiliated
by Lady O in an effort to bring them back to painful reality.

Director
Eric Edwards has made a good-looking, arousing vid with varied
camera angles, slick editing, good lighting and intense
performances from all.
